Food was not kept cold enough, hot enough, cooled fast enough, or cooked or reheated to the right temperature. Bacteria grow quickly in the "danger zone" between 41°F and 135°F, which makes this one of the most important food-safety checks.
A required permit, food safety certificate, trained manager, or posted sign was missing or not current. These show the business is following the rules and has trained staff.
Food came from an unapproved source, was missing required date marks or labels, or was past its use-by date. Knowing where food came from and how old it is helps prevent illness.
The business had issues with hot or cold running water, plumbing, drains, backflow prevention, or sewage disposal. Some of these, like no hot water, can force a temporary closure until fixed.
